aoonnnaaron Application filed July 5,

To all whom it'may concern:

Be it known that we, CLINT Haimronn and WILLIAM INMANpcitizens of the United States, and residents of Boyne City, 1n the county of Charlevoix and State of Mich gan, have invented certain new: an'd useful Improvements in Accelerators, of which the following is a full, clear, and exact 'ClQSCIlP tion.

This invention relates to accelerators,

especially adapted for use on internal combustion engines. i

Briefiystated animportant ob ectof this invention is to provide an accelerator for Ford motors having means whereby. the same is'operated automatically by the depression of either the clutch or reverse pedals. f i y A furtherobject is to provide an accelerator for internal combustion engines which. maybe applied totthe engine without'elaborately altering the construction of the same and which will eliect an apprec1- able economy in the consumption of fuel.

Other objects and advantages of thelinvention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application, and in which like numerals are employed to designate like parts throughout the same. 1 Figure 1 is a plan view of the improved accelerator applied, and

Figure 2 is a perspective viewof the same detached. i 1

In the drawing wherein for the purpose ofillustration is shown apreferred embodi monitor the invention, the numeral 5 designates' an internal combustion engine hav ing a carburetor 6 which in thi'scaseis controlled by an accelerator generally desig- 1921. Serial No. 482,481.

internal combustion engine 5is reversedand in this case also by increasing the pressure on the pedal 11 the driving connection between the engine and the rear wheel is tightened.

. The improved accelerator is formed from a length of round metal having one end portion formed witha bend 12 defining a U-shaped member. The said U-shaped member thus formed 'isprovided with an arm 14 rotatably connected to the transmission housing by means of a pair of spaced clips 7 16. The other arm 17 of the U-shaped member formedby the bend 12 has that portion adjacent the bend 12 arranged directly in advance of the pedals .10 and 111. Therefore, whenuthe pedals 11 are de pressed when throwing :the transmission either in low speed or reverse, the pedal engaging portion 20 of the arm 17 will be moved downwardly ina clockwise direction, moving the entire rod in the same direction. The arm 17 at one side of the U-shaped member is formed with an onset, disposing the terminal portionofthe arm above the pedal-engaging portion 20 and defining the foot contact portion 24. By offsetting the foot-engaging portion 24 with respect to the pedal-engaging portion 20 more accurate control over the carburetor may be exercised by the foot. Inother words, the footengaging portion is rendered: less sensitive than would be the case it the same was in line with the pedal-engagingportion 20'. it

The other end of the rod is offset, as indicated at 26; to define an attaching arm 28150 which a link 30 is connected. The for pedal 11 is depressed so as to engage the pedal-engaging portion 20 whereby the rod may be rotated in a clockwise direction for 1 opening the main'valve of the carburetor. Should it be desired to reverse the vehicle thepedal 11 is depressedand asthe driving connection between the engine and the rear wheels is tightened the engine is accelerated automatically. The same applies to the operation ofthe low speed pedal which is depressed for throwing the transmission into low speed. 3

,The pedal-engaging portion is braced by means of a transversely extending rod 38 welded or otherwise secured at its ends to the arms'formed by the bend 12. A second brace 40 is secured to the rod at opposite sides of one of the bearing members 16 and serves to strengthen the rod at the offset 42 intlie same. v -With.reference-to:the foregoing description'taken in connection with the accompanying dra'wing'it will be apparent that a foot accelerator constructed in accordance with this invention will be automatically operated when the foot pedals 10 and 11 are depressed.- Also. the foot-engaging portion 24: is within convenient reach of the operator and will. not interfere with the operation of the brake'46 since" the offset in the arm 17 disposes thefoot-engaging portion Qirearwardly of the brake pedal.

1 We claim: 1, An accelerator formed from a length of metal formed with a bend defining a pair of arms, one of said arms being formed with an offset defining pedal and foot-engaging, portions, andattaching means associated with the otherarm. I i

2; An accelerator formed from a length oflmetal formed with a bend defining a pair of arms, one of said arms being formed with an offset defining pedal and foot-engaging portions, attaching means associated with the other arm, and bracing means between said arms. i

'3. An accelerator formed from a length of metal formed with a bend defining a pair of arms, one of said arms being formed with ;tion defining a foot and a pedal-engaging portion, said offset also disposing said foot-.

engaglng portion in spaced parallel relation to said pedal-engaging portion, and an operating link connected to one of said arms.

6. An accelerator for internal combustion engines comprising a length of metal formed intermediate its ends with a bend defining apair of spaced parallel arms having offsets, one of said offsets defining a foot-engaging portion and a pedal engaging portion, a bracing device connected to one of said arms at opposite'sidesof the ofYse-tin the same, means rotatably supporting one of said arms, and an operating member connected to one of said arms.

6. An accelerator for motor vehicles comprising a pair of spaced arms, one of which is adapted to be directlyengaged by a plurality of 'the foot pedals of a planetary transmission, andmeans to rotatably sup port the other arm, said arms being arranged in parallel relation and transversely of themotor vehicle.

'7. An accelerator for motor vehicles com prising a pair of arms, one of which is adapted to be engaged by certain of the foot pedals ofav planetary transmission, and means to rotatably support theyother arm, one of said arms beingformedwith a bend defining a "foot engaging portion.

8. An accelerator for motor vehicles comprising a pair of arms, one of. which is adapted-to be engaged bycertain of the foot pedals of a planetary transmission, and means to rotatably supportthe other arm, one of saidarms being formed with a bend defining a footwengaging portion, and the other arm being formed with means whereby the same may be connected to a carbureter. i

' 9. An accelerator for motor vehicles comprising length ofmetal formed with a bend defining a pair of arms, one of which is adapted to 'be engaged by certain of the foot pedals of a transmission, and means whereby to rotatably support the other arm.

10. An accelerator comprising an arm having its intermediate portion ofi'set whereby to provide pedal and footengaging portions, the pedal and foot engaging portions being arranged in parallel relation.

11 An accelerator comprising an "arm having. its intermediate portion ofl'set whereby to-provide pedal and foot engaging portions, and means associated with said arm for supporting the same and connecting the arms to a carbureter.
